Answer :
Answer:
ans = 9 degree
Step-by-step explanation:
81 + (4x) + (5x+18) = 180 (The sum of all angles of triangle is 180 degree)
81 + 4x + 5x + 18 = 180
99 + 9x = 180
9x = 180 - 99
9x = 81
x = [tex]\frac{81}{9}[/tex]
x = 9 degree
Answer:
ans = 9 degree
Step-by-step explanation:
81 + (4x) + (5x+18) = 180 (The sum of all angles of triangle is 180 degree)
81 + 4x + 5x + 18 = 180
99 + 9x = 180
9x = 180 - 99
9x = 81
x = [tex]\frac{81}{9}[/tex]
x = 9 degree
